The NRH 4201-100 is a premium-grade spring handle that combines durability, functionality, and aesthetics. Crafted from SUS 304 stainless steel and finished with a sleek High Gloss Finishing, it offers superior corrosion resistance and a professional appearance. Integrated with a robust spring mechanism and a comfortable soft rubber grip, this handle features a 90-degree mechanical stop for stable lifting and an automatic spring-return action for space-saving storage. Weighing only 122g with a 245N (25kg) tensile load capacity, it is designed for reliable performance in demanding applications. Proudly bearing the NRH brand, it represents quality hardware from a trusted manufacturer.
Primary Applications
This handle is designed for high-quality applications where corrosion resistance, clean appearance, and reliable operation are required:
-
Premium Instrument Cases: Handles for precision measurement equipment, laboratory analyzers, and calibration standard cases.
-
Professional Audio/Video & Road Cases: High-end flight cases for mixers, amplifiers, and broadcast equipment.
-
Medical & Laboratory Devices: Sterilization containers, portable diagnostic units, and medical carts where hygiene and durability are critical.
-
Food Processing & Marine Equipment: Enclosures and cases in corrosive environments or where frequent cleaning is needed.
-
High-End Industrial Consoles: Control panels, server racks, and technical furniture requiring a sleek, durable handle.
How It Works (Operation Principle)
The handle operates on a precise spring mechanism. To use, simply pull the handle upwards; it will extend smoothly until it reaches the integrated 90-degree stop, locking into a stable position ideal for carrying. To store, release the handle—the internal spring automatically retracts it, allowing it to fold completely flat against the mounting surface. This provides a secure grip when needed and maintains a clean, low-profile appearance when not in use.
